Note a: The value is valid only if the conductors of the PE cable and AC power cable use the same
material. If the materials are different, ensure that the conductor cross-sectional area of the PE
cable produces a conductance equivalent to that of the area S/2. The specifications of the PE cable
are subject to this table or calculated according to IEC 60364-5-54.
Note b: You are advised to use a soft cable to prevent poor terminal contact due to the bending
stress of the cable. The cable diameter must comply with local cable standards. The factors that
affect cable selection include the rated current, cable type, routing mode, ambient temperature, and
maximum expected line loss.

Installing the PE Cable

•
It is recommended that the PE cable
be connected to a nearby PE point.
Connect the PE points of all
SUN2000s in the same PV array to
ensure equipotential connections to PE
cables.
•
To enhance the corrosion resistance of
a ground terminal, you are advised to
apply silica gel or paint on it after
connecting the PE cable.
